You can put this solution on YOUR website!
Ordered pairs are given with the x-coordinate first then the y-coordinate (i.e., (x,y)).
\n" ); document.write( ".
\n" ); document.write( "In your problem, you are given two ordered pairs -- the first is missing the y-coordinate and the second is missing the x-coordinate:
\n" ); document.write( "ordered pairs(0, )
\n" ); document.write( "and
\n" ); document.write( "(3, )
\n" ); document.write( ".
\n" ); document.write( "To find the missing coordinate, substitute the provided point into the given equation and solve for the missing point.
\n" ); document.write( ".
\n" ); document.write( "The first pair:(0, )
\n" ); document.write( "Here, they give you x is equal to zero. Substitute it in and solve for y.
\n" ); document.write( "y = 2x + 7
\n" ); document.write( "y = 2(0) + 7
\n" ); document.write( "y = 0 + 7
\n" ); document.write( "y = 7
\n" ); document.write( "First ordered pair is (0,7)
\n" ); document.write( ".
\n" ); document.write( "The second pair:(3, )
\n" ); document.write( "Here, they give you x is equal to three. Substitute it in and solve for y.
\n" ); document.write( "y = 2x + 7
\n" ); document.write( "y = 2(3) + 7
\n" ); document.write( "y = 6 + 7
\n" ); document.write( "y = 13
\n" ); document.write( "Second ordered pair is (3, 13)
\n" ); document.write( " \n" ); document.write( "
\n" );
